Application mea Marcha, v1909. serial No. 481,417.

To all 'whom t may concern:

Be it known that I, STANLEY W. LYMAN, a native born citizen ofthe UnitedStates, residing at Roberts, in the county of Carbon and State ofMontana, have invented new and useful Improvements in Railroad-Rails, ofwhich the following is a specification.

The invention relates to an improvement in railroad rails, and is moreparticularly directed to a rail lnadeup of a series of sections adaptedfor assemblage in rail form to provide a practically unbroken structure.y The main object of the present invention is the provision of arailroad vrail madeeup of a series of independent sections severally'lincluding the tread portion and the base portion, the terminals of thetread sections and of the respective base sections meeting in offsetplanes to provide a practically unbroken rail. j j

Another object of the invention is the combining with a yrail of thespecific structure named of a chair'plate adapted to vembrace and clampthe base sections of the rail together and supportthe same inthe roadbed, a rail tie being arranged for coperation with the railsintermediate theterminals of adjacent chair rails at proper gage.

The invention will be described in the following specifcation, referencebeing had particularly to the accompanying drawings, in which Figure 1is a side elevation of a rail constructed in accordance with myinvention. Fig. 2 is a longitudinal section of the same taken just abovethe securing bolts. Fig. 3 is a perspective of one inemberof the base.Fig. 4 is a perspective of the coperating member of the base. Fig. 5 isasection on the line 5-5 of Fig. 2. Fig. 6 is a sectional view partly inelevation illustrating the improved rail tie used with the railstructure.

Referring particularly to the accompanying drawings, my improved rail ismade lup of three sections, a tread section 1, a tread supporting basesection 2 and a tread clamping base section 3, both ofsaid base sectionscoperating with the tread section to form the completed rail. The treadsection is formedto provide the usual bar or tread ortion 4, from whichdepends a central and ongitudinally extending web 5, the under surfaceof the tread portion immediately adjacent and on opposite sides of theWeb 5 beplates` to maintain the ing formed to provide receiving groovesG, as clearly shown in Fig. 5.

The base of the rail is lmade up of two sections for convenience termedthe tread supporting section and the tread clamping section. The treadsupporting section 2 is formed to provide a laterally extending basesection 7 from which projects an upwardly extending wall 8 formed at theupper end to fit within one Iof the grooves 6 in the tread portion. Thewall 8 is designed to abut and snugly fit the relatively outer surfaceof the vweb -5 being formed below the web with a laterally extendingshoulder 9 designed to underlie and directly engage the lower edge ofthe web projection 5. The shoulder 9 is coextensive in width with thethickness of the web projection, and beyond said shoulder the section 2is formed with a second shoulder l0 of somewhat less width than theshoulder 9 and projectedat an incline to said shoulder, said shoulder 10being arranged below the shoulder 9. From the edge of the shoulder 10the section 2 of the rail base is extended downward at 11 into a planewith the lower surface of the section and preferably at an angle -tosaid surface, as clearly shown in Fig. 5.

The clamping section 3 of the base is formed V,to provide a lateral baseange 12 vcorresponding to the flange 7 of section 2 and a verticallyextending wall 13 designed to t at its upper end within the remaininggroove 6 of the tread portion to snugly bear throughout its lengthagainst the web projection 5 of saidtread portion. The lower innersurface of the section 3 of the base is formed to engage the shoulder 10and fit against the inclined surface 1l of the section 2, whereby saidparts coperate to cffectively clamp the tread portion between them. Inthe inner surface of the section 3, at the point approximatelycorresponding to the relatively lower edgeof the web proj jection 5, thesection 3 is formed with a longitudinally extending groove or channel14.

This groove, when the sections are assembled, is, of course, closedbythe adjacent .surface of the web portion 5 and the sections 2, and isprimarily adaptedfor the reception of a bonding wire or for service as ahousing for power wires. Each of the sections 2 and 3 are formed in therespective walls 8 and 13 with apertures 15, preferably arranged in acentral pair and singly adj acent each end of the section. The outersur- :tace of section 3, which is the inner section, between the pair ofopenings 15 is channeled at 16 to receive cross bars 17 of a U-shapedretaining bolt 18 designed to pass through the respective sections andinterposed web projection of the tread portion. By the groove andsurface adjacent the openings 15 the bolt is more securely held and morereadily tightened. The respective sections are assembled in offsetrelation, that is the ends of one section, as 2, are disposedintermediate the ends of the remaining section, as 3, while the ends ofthe respective tread portions are arranged intermediate the ends of therespective sections. rIhe respective base sections and tread portionsthus break joint throughout the entire length of the track, so that therail is in effect continuous and is not capable of transverse separationat any one determined point.

It is obvious from the construction described that when desired eitherof the base sections or tread portions may be removed at will andsubstituted by others, this construction permitting the convenientrenewal of either of said sections when desired and particularly theconvenient renewal of the tread portion as the same becomes worn in use.

The rail of the present invention is designed particularly forcoperation with a road bed forming the subject matter of a concurrentapplication, and to particularly adapt this rail for cooperation withsuch bed I provide a chair plate 19 designed to underlie the respectivesections of the base and having inturned edges 2O to clamp over the freeedges of the base flanges 7 and 12 of the respective sections 2 and 8.The relatively lower surface of the chair plate is inclined in V-form,as at 21, for use with the road bed described.

In connection with the rail structure described I use a rail tie bywhich the respective rails are maintained at gage. This rail tie isarranged intermediate the ends of the adjacent sections of the chairplate and is adapted to directly engage the sections 2 an'd 3 of thebase member. In detailed structure the rail tie comprises a coupling 22having a central body 23 of angular contour in section to provide foroperating the coupling by a wrench or the like. Sleeves 241 project inopposite directions from the body 23 and are interiorly threaded at 25for the reception of tubular members 2G to the outer ends of which arefixed blocks-27 having overhanging lips 28 to engage the edges or' oneof the sections of the base member.

Mounted within the tubular members 26 are rods 29 arranged to extendthrough the blocks 27 and terminate beyond the same in inclinedprojections 30 to coperate with the overhanging lips 28 and to engagethe free edge of the section of the base opposing the section engaged bylip 28. The inner ends of the rods 29 are threaded at 31 within athreaded bore 32 formed centrally of the coupling body 23, so that byturning said body the parts may be adjusted to move the rails to or fromeach other and thereby set the track at desired gage.

A simple means, as a yoke 33, is arranged for connection with thecoupling 22 for securing said coupling against independent longitudinalmovement relative to the tie or other road bed structure.

The rail structure herein shown provides a sectional rail in whicheffective clamping of the tread portion is secured in a manner to permitthe convenient removal of said tread portion it desired for renewal.Furthermore, the particular chair plate described adapts the rail forcoperation with the road bed structure in a manner to prevent lateraldisplacement of the rail while the tie member maintains the rails atelective gage throughout the length of the track.

Having thus described the invention what is claimed as new, is

1. A sectional rail including a base member made up of two sections, atread portion arranged to lit between and be engaged by said sections,one of the base sections being formed to entirely underlie and supportthe tread portion, both of said base sections being formed withcooperating interlocking portions below the tread portion, and a chairplate underlying and clamping the sections together.

2. A sectional rail including a base member made up of two sections, atread portion arranged to lit between and be engaged by said sections,one of the base sections being formed to entirely underlie and supportthe tread portion, both of said base sections being formed withcooperating interlocking portions below the tread portion, and a chairplate underlying and clalnping the sections together, the lower surfaceof said chair plate being inclined in two distinct reversely disposedplanes.

In testimony whereof I aliix my signature in presence of two witnesses.
